Embodiment
In the first embodiment, with reference to Fig. 1-3, the invention provides a kind of sensor assembly that motor vehicles are opened control gear that is used for.Described module is equipped with first displacement transducer of control one closing of circuit.Module also has one second sensor, and it is read by described circuit supply and/or by described circuit.When not activating, first sensor electricity isolation sensor module; On concrete, second sensor does not consume any energy.So the energy consumption of module is zero.When first sensor activated generation, the closing of circuit and second sensor were activated.It just can provide to repeat to survey and confirm the order of sending to the lock that this module is housed then.
Fig. 1 is the sensor assembly perspective diagram of an embodiment of the present invention.Module 2 has a shell 4, and this shell utilizes erecting device to be assemblied on the resistor of a unlatching control gear.In the example of Fig. 1, these erecting devices are made of 6,8 and short columns 10 of two tongue pieces.Described short column is nearer and far away with another at a distance of one of two tongue pieces, is used to locate a groove, will make an explanation to this with reference to Fig. 6.Wherein a tongue piece 8 has a backstop 12 for another tongue piece 6 of arc; By inserting arc tongue piece 8 in the groove and making tongue piece 6 elastic deformations and it is pushed in another groove, be installed on the control gear thus.When sensor assembly put in place, described backstop can make it remain on its position.Particularly when erecting device be set to stop any by module position produce chaotic the time, the erecting device in this example beyond the tongue piece also can be used, also can be without locating slot.
Module 2 has a first sensor, and it is a displacement transducer.In the example of accompanying drawing, displacement transducer is a switch, when the moving component displacement, and this switch transition state.Described moving component is installed in the distortion corrugated tube 14, and its motion is along the direction of 16 indications of arrow among the figure.Do not consider its state exchange, switch can be used as the closure that first sensor controls control circuit.In example, circuit disconnects when first sensor does not activate, when first sensor is subjected to when mechanically actuated closing of circuit along the direction that is deposited to shell.First sensor is opened control assembly or a special cam mechanically activates in this way.
Description by the example remainder illustrates, and a mechanically actuated switch only is an example with displacement transducer control circuit closure.Concrete, a reed switch can be used for substituting switch, and this class switch is made of a glass bulb that includes two mutual close reeds, and two reeds can be in contact with one another under the action of a magnetic field.Contact between reed has the effect of closed circuit.In this case, this sensor detects the displacement of the magnet that is equipped with a moving component in the control gear.
Under above two kinds of situations, even first sensor also can detect displacement when not powering.
Module 2 also has one second sensor.Second sensor can be displacement, stressed, distortion or induction pick-up.In the example of accompanying drawing, it is a hall effect sensor.The induction pieces 18 of second sensor illustrates at the side of shell.Second sensor is by circuit supply, and the closure of circuit is controlled by first sensor.In case power supply, second sensor just can be surveyed the displacement of another parts, stressed, distortion or approaching.
On second sensor is concrete can be:
One switch;
One hall effect sensor is as shown in Fig. 2,3;
One reed switch is shown in example among Fig. 4;
One optical displacement sensor;
One capacitive character is near acquisition sensor;
One is ultrasonic near acquisition sensor;
One inductive variableimpedance or vortex induction sensor;
One resistive, optics, magnetic or other type coding device;
One deformation-sensor, for example strainometer or piezoelectricity barrier film;
One force sensor, for example piezoelectricity, magnetoelasticity or strain-gage pickup;
Two sensors preferably use different technologies to reduce its common risk that lost efficacy.
The following operation of module among Fig. 1.When first sensor did not activate, module was in idle.Under this state, circuit disconnects and the not power supply of second sensor.When the mechanical effect of first sensor by moving component activated, corrugated tube 14 shrank and the first sensor closed circuits.This mode has the effect that starts second sensor.According to its mode of operation, second sensor can be surveyed the displacement of another parts, stressed, distortion or approaching like this.
As the explanation of reference Fig. 6-9, but described module can be used for the open control mechanism of motor vehicles opening assembly.Allow when opening, in electronic system from its stand-by state " awakening " and where necessary, the signal that first sensor is passed on is used to trigger opening function.The signal of second sensor is used to make and starts lock and open the command execution of motor or come into force.
Described module has following advantage, and the existence of first and second sensors provides redundant and guarantees to open the reliable detection of order in the module.On concrete, this redundancy has reduced electronics and has opened the spontaneous of lock system and open: first sensor fault and indication activate-and as the example in the accompanying drawing, if moving component continues to provide reliable actuating indication at low level-second sensor.Opposite, if second sensor fault and indication activate, unless the first sensor actuating, it will be left in the basket.This mode prevents spontaneous generation of opening and the dangerous appearance that activates, spontaneous the opening when vehicle moves for example, and spontaneous the opening when vehicle is parked on the slope, or the like.
And, when vehicle is parked-for example at long term stop field-first sensor disconnecting circuit.Sensor assembly and control electronic circuit thereof do not consume any energy, and this accumulator that prevents more or less discharges rapidly.The actuating of first sensor comes start-up system control electronic circuit by closed circuit.
At last, described module can be according to the kind of open control mechanism and is easily renovated and be improved on the open control mechanism.If reed switch as first sensor, simultaneously, can install to a magnet to open and open on the control gear; If second sensor is a hall effect sensor, and is so same as described above.In any case, shown in Fig. 6-9, identical parts are used to produce the different control of opening.So described sensor assembly causes diversified reducing.
Fig. 1 only is an example.On concrete, first sensor preferably is controlled to be: when first sensor does not activate, and disconnecting circuit, or in other words, when activating, closed circuit.If first sensor has a spring, then guarantee when first sensor does not activate or open control mechanism when idle spring be in relaxation state.When first sensor is idle, can make its permanent closed circuit; In the case, open when being controlled at idle state when opening, first sensor activates with disconnecting circuit.In other words, first sensor is when no longer opening control control circuit closure then when activating by opening.Under two kinds of situations, first sensor guarantees that circuit is closed when the user acts on the unlatching open control mechanism.
Fig. 2 and 3 illustrates the circuit diagram of module, and it is that hall effect sensor is an example with second sensor.These circuits do not illustrate the closed manners of first sensor control circuit, and the electronic circuit of reading of first and second sensors just is shown.
Example among Fig. 2 illustrates first sensor 30, is illustrated as a switch.This circuit is by four end points 32,34,36 and 38.Supply voltage imposes on the end points 38, end points 34 ground connection.End points 36 provides one to represent the signal of second sensor, 40 states and end points 32 provides a signal of representing first sensor 30 states.First sensor is serially connected between two end points 32 and 34.Hall effect sensor ground connection 34.The power supply end points is connected on the end points 38 by a resistance 48 and a diode 50.One of Zener diode of ground connection end is connected between sensor 40 and the resistance 48.Protectiveness electric capacity 52 be connected to and end points 38 between.Resistance 48 and Zener diode 46 act as overvoltage protection, and diode 50 protections are lived sensor not by the infringement of the reversal connection of battery utmost point position, and electric capacity 52 protects sensor not discharged and electrostatic discharge damage.The state end of hall effect sensor is connected to by a resistance 42 and reads end points 36; Once more, protectiveness electric capacity 44 be connected to and 36 of end points.Resistance 42 is as overvoltage protection and electric capacity 44 protection sensors are not discharged and electrostatic discharge damage.End points 36 provides one to represent the signal of second sensor, 40 states and end points 32 provides a signal of representing first sensor 30 states among Fig. 2.
Example among Fig. 3 is similar to the example of Fig. 2, but it adopts hall effect sensor and is used to provide the method for power supply with end points 38 conllinear of reading.Circuit connection among Fig. 3 does not have resistance 42 and electric capacity 44; The end points of reading of hall effect sensor is connected on its power supply end points by a resistance 54.Measured value at end points 38 voltages can be determined sensor states.
Example right and wrong among Fig. 2 and Fig. 3 are determinate.
Figure 4 and 5 show second embodiment of the present invention.In this embodiment, even sensor assembly has two sensors that also can survey displacement when not powering, they consume or consumed energy not hardly.Preferred sensor adopts different Detection Techniques to reduce its common risk that lost efficacy.When not activating, consume seldom or not with regard to the consumed energy, when it is idle, do not need one of this two sensors that another sensor electrical is isolated with regard to two sensors.Once more, but one of two sensors be preferably used in and start vehicle opening assembly electronic circuit.This mode reduces electronic circuit and starts the number of end points and simplify its structure.
Fig. 4 shows the sensing circuit block diagram.In the example of Fig. 4, first sensor 66 is a switch, and second sensor 68 is a reed switch.The circuit of Fig. 4 has three end points 60,62 and 64.First sensor 66 is installed between end points 60 and 62, and second sensor 68 be installed in end points 64 and 62 and with a protectiveness resistance 70 polyphones.End points 62 ground connection and end points 60 and 64 is used for the pickup state.
Fig. 5 illustrates another embodiment.As the example among Fig. 4, two sensors 72,74 is for consuming seldom or not catabiotic displacement transducer.Be illustrated as the possible fit of carrying out analog detection of a kind of sensor.Each sensor is contacted with resistance 76,78 respectively; Preferred resistance has different resistances.Voltage V is applied on the end points of two series circuits in parallel.Be appreciated that voltage by the decision of the state of two sensors, and its value is not having, is being different during one or two sensor energize.The circuit of Fig. 5 is one and is having of displacement detection of the redundant simple analog circuit of surveying.
Module among the image pattern 1-3 is the same, but the module in the Figure 4 and 5 is advantageously used in the control of opening of motor vehicles opening assembly.Favourable, in the case, two sensors is used for surveying the motion of same parts, for example door handle or column cap.Module provides redundant detection in this way; As the example among Fig. 6-9, the motion of parts can directly affact on these two sensors.Also can provide intermediate member, the motion of door handle or column cap can directly or indirectly be affacted on two sensors.But Fig. 6-9 is illustrated in the example that the motor vehicles opening assembly is opened utilization sensor assembly in the control.In these examples, module is used for surveying the motion of same movement parts, as the flexible handle of control gear.Control system in Fig. 6 and 7 is the movable pull handle of control gear.Fig. 8 and 9 is the control of a foot-operated handle.In the example of Fig. 8 and 9, sensor assembly is surveyed the motion of a single part, and these parts are one and open pedal.In the example of Fig. 6 and 7, sensor assembly is surveyed the motion of a pull handle; The motion of pull handle by the second sensor direct detection and by first sensor by its be subjected to one open lever be used for detect indirectly.No matter detection is directly or indirectly, sensor assembly all provides redundant to single part and surveys.
Fig. 6 illustrates the decomposition diagram that an outside pull handle is opened control gear.But the seal element 102 that outside unlatching control gear shell 100 inserts between opening assembly and shell in addition in the drawings as seen.Shell has the backstop 104 of a cable protective sleeve 106.It has the hole 108 that is used for supporting the axle 110 that rotarily opens lever 112.Being used for recovering lever is installed in to the returning spring 114 of rest position and opens between lever and the shell.Shell also has and is used for installing the device 116 of module as shown in Figure 1; In example, this device has two grooves and the hole by short column.Accompanying drawing illustrates module 118 and its cable bundle 120.Snap seat 122 is fixed on the shell by a screw 124.At last, accompanying drawing illustrates a pull handle 126 and one by the opening cam 128 of the screw retention of label not.Pull handle can be equipped with a magnet 130.Cable end 132 can be by opening lever actuated, and sensor assembly is to similar shown in Fig. 1-3, and its difference is the same side that hall effect sensor is not arranged in module.
Multiple parts among Fig. 6 can be used for a machinery and open and be provided with.In the case, pull handle 126 is installed on the shell, opens lever 112 and installs with its spring 114, and cam 128 is installed on the lever, and the snap seat has also been installed, and protective sleeve 106 is placed on the shell and cable end is placed in the unlatching lever.Wherein both do not adopted sensor assembly 118 not adopt magnet 130 yet.This lock is Purely mechanical.The rotation of pulling door handle acts on by cam 128 and opens on the lever 112 and resist mutually with returning spring power.Lever pulling cable one end, it has caused-suppose implementing in advance not having the device of description to carry out safe release-lock here being opened.When the user decontrols pull handle, returning spring activates also and takes back lever, and pull handle is got back to idle state then.
Parts among Fig. 6 can be used for the electronic setting of opening, and it has the electronic type opening mechanism by switch control, and for example it is installed in the end that cable has lock.In this way, the actuating of opening is established in the motion control of cable by cable.In the case, still do not need sensor assembly.
Once more, the parts among Fig. 6 can be used for the electronic setting of opening, and have the control opening mechanism.Sensor assembly 118 is installed on the shell and is connected in cable bundle.If the redundancy of requirement, magnet 130 just is installed on the pull handle.The startup of electric opening motor is controlled by the sensor in the sensor assembly.As recommending among FR02-01698 and the FR02-01699, cable can be used for the actuating that electronics is opened.In the case, sensor assembly is used to control electric opening.
At last, the parts among Fig. 6 can be used for a pure electronic setting of opening.In the case, except that not identical with its assembling the cable.Fig. 7 illustrates the outside partial cross section figure of control gear when rest position that open.Shell 100 has the pull handle 126 and the cam 128 of magnet 130, open in addition lever 112 and sensor assembly 118 all in this figure as seen.The pulling pull handle makes lever center on its rotation of 110 by cam 128, and this rotation resists mutually with the acting force of spring.The lower reaction of lever is placed on the first sensor at top in sensor assembly.It has the effect of closed sensor modular circuit and powers to second sensor.Simultaneously, the second sensor the place ahead motion of magnet 130 in module 118, the redundant information that provides pull handle to activate.
When the user decontrols pull handle, spring 114 brings back to rest position with lever 112 and pull handle 126.Lever 112 stops to first sensor 118 effects, and module recovery is to idle state, and the power supply of hall effect sensor disconnects.It must be noted that in other embodiments, can remove by the inversion set that lever 112 and cam 118 are formed.
Like this, the corresponding magnet with it of sensor assembly is retrofitted to according to the type of opening control gear and opens on the control gear.
Fig. 8 and 9 is the simulated representation of Fig. 6 and 7 diagrammatic sketch, and it is designed to a foot-operated handle.Fig. 8 illustrates the outside decomposition diagram of opening control gear.But the outside control gear shell 140 and in the drawings as seen opened at the installation seal 142 of opening assembly one side.This shell has a backstop 144 that is used for cable protective sleeve 146.It has the hole 148 that is used for supporting the axle 150 that rotarily opens pedal 152.Being used for recovering lever is installed in to the returning spring 154 of rest position and opens between pedal and the shell.Shell also has and is used for installing the device 156 of module as shown in Figure 1; In example, this erecting device has two grooves and the hole by short column.Accompanying drawing illustrates module 158 and its cable bundle 160.Snap seat 162 and snap cam 164 are fixed on the shell.At last, open the used seal 168,170 of pedal 152 shown in the figure.Can see the pedestal 174 that parts on the pedal form an opening cam 172 and a magnet 176 in the drawings.One end 178 of cable is by opening pedal-driven.Sensor assembly 158 is similar to the module among Fig. 1-3.
As the explanation in reference Fig. 6 and 7, the multiple parts among Fig. 8 can be used in different the setting, comprise that machinery opens, has electronic the opening of being opened by the switch electric control, electronic the opening of being opened by electronic or pure electric control.
Fig. 9 shows the vertical section figure of the outside unlatching control gear among Fig. 8, and it is the setting that has sensor assembly 158.Accompanying drawing is depicted as the outside control gear of opening at its clear position.Sensor assembly 158 with hall effect sensor search coverage 18 in the drawings as seen.Accompanying drawing illustrates and has the outside unlatching control gear shell 140 of opening pedal 152 and sealing 168.But the outside 180 of opening assembly in the drawings as seen.The rest position that illustrates in the drawings, pedal 152 is against shell.The cam that parts 172 form does not act on the corrugated tube of sensor assembly, so second Hall element is not activated.Pulling is opened pedal and is caused it to turn clockwise in the drawings.The parts 172 that form cam in the pedal act on the first sensor, but with this electronic circuit that starts opening assembly, are specially to second sensor (being hall effect sensor) and power.Simultaneously, magnet 176 is thrown off from sensor 18, confirms to open with this.For pure electronic opening, activate to open motor.In the example of Fig. 9, the motion continuation of parts 172 and the shell of sensor assembly are not the ends that stroke stops, and this mode can reduce the stress on the module.Also can allow module that pedal 152 is carried out travel limits.
The switching sequence that is appreciated that two sensors from Fig. 6 to 9 can conversion.Like this, second sensor can be from first state exchange to the second state before the first sensor closed circuit.After closing of circuit, whether second sensor is in that second state is detectable to be gone out.Selectable in addition, if the conversion of second sensor needs to survey, the module working method is: the second sensor transition status after first sensor is subjected to acting on.Last scheme is near acquisition sensor-optics, capacitive character or ultrasonic-advantageous particularly, and its transition status is also surveyed like this.
Certainly, the present invention is not only limited to the embodiment of describing as example.So in example, the present invention is described as it and is applied to opening of car door; But and its general opening assembly, particularly back case lid or car door that is applied on any vehicle.Sensor assembly of the present invention can be used in the control gear with different structure shown in Fig. 6 to 9.Described module can also be used to have the control gear of its rest position at the door handle of centre, and it can move to two relative directions, for example the tail gate door handle of the 806 type cars of being made by beautiful (Peugeot).In the case, can to leave in the middle of it rest position at door handle one promptly actuatable for first sensor; Second sensor is surveyed the motion of door handle at single direction.Can be arranged to: it for the pure electronic control of opening, and is pure machinery control in another direction of motion on a direction of motion, and that a motion hook opening assembly is remained on the mechanism of full open position is used but such is controlled to be.Example among Fig. 6 to 9 is illustrated in the motion that the sensor assembly among Fig. 1 to 3 is used for surveying parts-a pull handle redundantly or opens pedal.Sensor assembly in Figure 4 and 5 can be used for opening control gear as the outside at Fig. 6 to 9 equally.In addition, the sensor assembly among Fig. 1 to 3 is at first surveyed the displacement of a moving component, is an other actuating then.For example, this module can utilization on an equal basis in having the control gear of fixedly door handle and column cap, the control gear of using on the Mini of its manufacturing type car as BMW; In the case, the first sensor and second sensor can be surveyed the motion of plunger, as the explanation among reference Fig. 6 to 9.Whether the hand that second sensor can be surveyed the user is put on the fixing door handle; In the case, second sensor can be capacitive sensor, has only when first sensor is activated by column cap just to start.
In the example of aforementioned proposition, the invention process can also be applied to an inner control gear of opening in an outside control gear of opening.
